Definitions

  • the invention relates to a method for operating a network node in a vehicle and, more particularly but not exclusively, to a car comprising the network node.
  • a direct communication between a mobile unit located within the passenger cab and a base station of a radio communication network outside the passenger cab is nearly impossible or requires an enhancement of transmission power at the mobile unit as well as at the base station. This reduces the operation time at the mobile unit until a next charging process is required and is accompanied with large energy consumption at the mobile unit as well as at the base station. Therefore, a car may be equipped with an external antenna for example mounted on a roof of the car and a transceiver unit connected to the external antenna.
  • the transceiver unit is adapted to receive radio frequency signals from a radio communication network and is adapted to transmit radio frequency signals to the radio communication system.
  • the transceiver unit is further adapted to convert the radio frequency signals into further frequency signals based on a short range radio access technology such as Bluetooth or WLAN.
  • a short range radio access technology such as Bluetooth or WLAN.
  • Mobile units located inside the passenger cab can exchange information indirectly with the radio communication network via the short range radio access technology and the transceiver unit of the car.
  • Such a communication technique requires that the mobile unit comprises in addition to a long range radio interface such as UMTS at least one short range radio interface.
  • the car may be equipped with a GSM or UMTS repeater, the external antenna connected to the GSM or UMTS repeater and an internal antenna located inside the car and connected to the repeater.
  • Radio frequency signals received in downlink direction from a base station at the external antenna are amplified by the repeater and are transmitted via the internal antenna to the mobile unit located inside the car.
  • the external antenna is linear polarized and the internal antenna is circular polarized, interferences between radio frequency signals based on a communication between the base station and the external antenna and radio frequency signals based on a communication between the internal antenna and the mobile unit cannot be fully avoided.
  • the way of operating a network node of a vehicle affects user satisfaction and network coverage of a radio communication network.
  • the object is achieved by a method for operating a network node in a vehicle, the method comprising the steps of operating a first radio interface of said network node with a radio access technology of a radio communication network as a radio interface of a mobile unit, and operating a second radio interface of said network node with said radio access technology as a radio interface of a base station of said radio communication network towards at least one mobile unit located in the vehicle.
  • the object is further achieved by a network node adapted to perform the method and by a vehicle comprising the network node.
  • the invention provides a first benefit of providing a base station within a passenger cab of a vehicle.
  • the invention provides a second benefit of not requiring any additional short range radio interfaces at the mobile units and thereby reducing costs (e.g. CAPEX) and energy consumption for the mobile units.
  • the invention provides a third benefit of requiring no user intervention at the mobile unit, because no additional radio interface needs to be activated at the mobile unit. Thereby, user perception can be improved.
  • the invention provides a fourth benefit of allowing a handover from a radio cell of a stationary base station of the radio communication network to the radio cell of the network node inside the vehicle, if a passenger gets into the vehicle or handover from the radio cell of the network node to the radio cell of the stationary base station of the radio communication network, if the passenger gets off the vehicle.
  • the method further comprises the steps of verifying an operation state of the vehicle, and performing the operating step for the first radio interface and the operating step for the second radio interface, if the vehicle is operated by a vehicle driver.
  • the preferred embodiment allows operating the network node with the operating steps only, if the vehicle is moving around. This allows to reduce the energy consumption and to avoid any unnecessary radiation.
  • the method further comprises the steps of applying first radio frequency signals of a first frequency range between at least one stationary base station of the radio communication network and the first radio interface, and applying second radio frequency signals of a second frequency range separated from the first frequency range between the second radio interface and the at least one mobile unit.
  • the further preferred embodiment has a benefit of avoiding any interference between the first radio frequency signals and the second radio frequency signals by using different frequency ranges.
  • the first frequency range is below the second frequency range. This allows the first radio signals to extend a longer distance from the stationary base station to the first radio interface of the network node than the second radio signals, which can be limited to a passenger cab of the vehicle or can be restricted to a limited area around the outside of the vehicle and thereby limit any possible interference with radio frequency signals transmitted directly between stationary base stations and further mobile units to a small restricted area.
  • the first frequency range is below 1 GHz and the second frequency range is above 2 GHz.
  • This large frequency distance provides an even better decoupling between the first radio frequency signals and the second radio frequency signals and should avoid any interference processes.
  • the second radio frequency signals can be restricted to a small cross sectional area of a few tenfold metre around the vehicle and the first radio signals are able to spread across a cross sectional area of more than one kilometre limiting a number of stationary base stations of the radio communication network to cover a specific area.
  • the first radio frequency signals and/or the second radio frequency signals are transmitted with a MIMO transmission scheme.
  • This provides a high data throughput for all kinds of real time applications such as video download, gaming or video teleconferencing and thereby improves end-user experience.
  • the second radio interface of the network node is a multi-standard radio interface adapted to provide the radio access technology and at least one further radio access technology.
  • This allows using mobile units belonging to different radio access technologies such as 2G (e.g. GSM, GPRS), 2.5G (e.g. EDGE), 3G (e.g. UMTS), pre-4G (e.g. LTE) or 4G (LTE-Advanced).
  • 2G e.g. GSM, GPRS
  • 2.5G e.g. EDGE
  • 3G e.g. UMTS
  • pre-4G e.g. LTE
  • 4G Long Term Evolution-Advanced
  • the network node further comprises a wireline interface of a wireline access technology and the wireline interface is adapted to provide a data connection towards the radio communication network.
  • This further preferred alternative provides the advantage of offering a further connection type between the network node and the radio communication network in addition to the wireless connection type provided by the first radio interface.
  • a vehicle comprising the network node, a first antenna system mounted externally to the vehicle and connected to the first radio interface and a second antenna system mounted internally within the vehicle and connected to the second radio interface may be any type of automobile such as a car, a bus or a lorry.
  • the vehicle is adapted to operate the first radio interface with a radio access technology of the radio communication network as a radio interface of a mobile unit and to operate the second radio interface with the radio access technology as a radio interface of a base station of the radio communication network towards the at least one mobile unit located in the vehicle in a first operating mode, if the vehicle is operated by a vehicle driver and the vehicle is adapted to operate the first radio interface and/or said second radio interface as a radio interface of a base station towards the at least one mobile unit in a second operating mode, if the vehicle is parked.
  • the second radio interface of the network node can be applied as a femtocell for passengers of the vehicle.
  • the first radio interface of the network node can be applied as a hotspot for subscribers of the radio communication network staying nearby the parked vehicle.
  • the operator of the radio communication network may offer a discount to the owner of user of the vehicle for offering the vehicle as a hot spot.
  • the vehicle comprises a port and a data connection between the port and the wireline interface and the first radio interface is adapted to switch from the first operating mode to the second operating mode, if the vehicle is connected via the port and a cable to a fixed backhaul link of the radio communication network.
  • the switching between the first operating mode and the second operating mode is done automatically, when the cable is connected to the port.
  • the vehicle is an electric vehicle
  • the port is integrated to a charging port of the electric vehicle
  • the first radio interface is adapted to the switch from the first operating mode to the second operating mode, if the electric vehicle is connected via the charging port to a charging station.
  • Figure 1 shows on the left-hand side a vehicle VH.
  • the vehicle VH may be an automobile such as a car, a lorry or a bus.
  • the vehicle VH is shown in Figure 1 exemplarily as a car.
  • Window panes of the vehicle may be coated with a metal coating such as chrome for reflecting shafts of sunlight and blocking radio frequency signals from the outside to the inside and from the inside to the outside of the vehicle VH.
  • the vehicle VH comprises a network node NN, which may be located for example below a roof of the vehicle VH. Alternatively, the network node NN may be located for example in a front part or a rear end of the vehicle VH.
  • the network node NN comprises a first radio interface and a second radio interface (not shown in Figure 1 for simplification).
  • a first antenna system ANT1 is mounted externally to an auto body of the vehicle VH preferably at the roof of the vehicle VH and connected to the first radio interface and a second antenna system ANT2 is mounted within the vehicle VH (this means within the internal space formed by the auto body of the vehicle VH) preferably within the passenger cab and more preferably at the roof of the vehicle and connected to the second radio interface.
  • the network node NN further comprises means for operate the first radio interface RI1 with a radio access technology of a first radio communication network RCN1 with a functionality of a radio interface of a mobile unit.
  • This allows, that the first radio interface is able to set up a global radio link GRL between the vehicle VH and a first base station BS1_1 of the first radio communication network RCN1 similar to a conventional mobile unit directly setting up a radio link to one of the base stations BS1_1, BS2_1 of the first radio communication network RCN1.

  • the network node NN For getting the network node NN completely in the first operating mode, in a first phase, the network node NN searches for any base stations BS1_1, BS2_1 of the first radio communication network RCN1. If one of the base stations BS1_1, BS2_1 is in operating distance, the network node NN may perform a conventional registration process of a mobile unit with the first radio communication network RCN1 by using authentication and registration information stored on the SIM card SIM_NN of the network node NN.
